To select a bank of prograrns, hold the [PROGRAM ]switch, press [BANK] key, and
enter the appropriate bank number using the O through 9 keys. The bank
command will be transmitted when the [PROGRAM] switch is released. The [INC]/
[DEC] keys may be used instead of entering the bank number.
Control # Commands:
There are 127 controller functions that are rnade up of continuous and switch
control commands. See Figure # 3. The most commonly used controllers are
aftertouch, pitch, modulation, volume and pan. Many expensive keyboard
controllers offer aftertouch, which allows expressive control of sound sources. The
ST-900 allows the same expression via [WHEEL A]. Aftertouch, pitch,
(1 through 16). Refer to the sound source s owners manual for this procedure.
3) Connect a momentary footswitch, which circuit is normally open, to the sustain
input jack clearly marked SUSTAIN located next to the MIDI jacks. We recommend
a VFP-1/10 (piano-like sustain pedal) available from Music Industries Corp.
4) Connect a control voltage pedal for volume in the jack clearly marked VOLUME
located next to the sustain jack. We recommend a VP-26 (expression pedal)
available from Music Industries Corp.
Once all connections are in place, press the power switch to the ON position.
TOP PANEL:
See Figure #2. You will notice on the left a dedicated pitch and a programmable
second wheel, rnarked [WHEEL A]. With [WHEEL A] you may assign aftertouch,
pitch, modulation, volume and pan as well as any controller (O - 127).
To the right of the wheels there are four switches. These switches are used for
program change, channel assignment, transposition and programmable wheel
assignment. Eighteen black keys on the keyboard are used for special MIDI
functions. The first five are used for [WHEEL A]. Notice, [AFT], [PITCH], [MOD],
[VOL] and [PAN]. These keys represent aftertouch, pitch, modulation, volume and
panning. The next 10 black keys represent a numeric key pad for program changes
and channel assignments. The following two black keys are used for increment and
decrement of a program change. [INC]/[DEC] will also change the controller
number. The last key is used for selecting a bank. More on this in the next section.
OPERATION:
Getting around the ST-900 is very simple. However, you must know certain basic
MIDI theory before it can make sense.
Base Channel:
There are l6 different channels in the MIDI specification that can be accessed
modulation, volume and pan can be accessed by the corresponding black keys,
,while all the remaining control functions can be accessed by the number or
[INC]/[DEC] keys.
To assign the programmable wheel press and hold the Control # switch. Enter the
desired controller number on the numbered black keys, or use the [INC] / [DEC]
keys, then release the control # switch. Look at the list in figure #3, try them out. If
you are having problems, chances are the sound source does not have that feature.
Sometimes you might get undesirable results. At this point it might be best to reset
your sound source (see sound sources owners manual) and shut off the ST-9OO,
then turn it back on again. This will reset the ST-900 to base channel #1, the control
wheel to modulation and no transposition.
